چکیده
A binary stochastic neuron (BSN) or a probabilistic bit (p-bit) randomly fluctuates between digitized “0” and “1” with controllable functionality of time-averaged value. Such an unconventional is the most essential building block for recently proposed neural networks computing. Here, we experimentally implement magnetic tunnel junction (MTJ) BSN, relaxation times on order tens milliseconds that can be modulated by current-induced spin-transfer torque. The NIST Statistical Test Suite (800-22a) used to verify true random number generation BSN-MTJ device. Our results suggest possibility using artificial BSN MTJ device in neuromorphic applications as well

Magnetic Tunnel Junction Mimics Stochastic Cortical Spiking Neurons
Brain-inspired computing architectures attempt to mimic the computations performed in the neurons and the synapses in the human brain in order to achieve its efficiency in learning and cognitive tasks. In this work, we demonstrate the mapping of the probabilistic spiking nature of pyramidal neurons in the cortex to the stochastic switching behavior of a Magnetic Tunnel Junction in presence of t...
متن کاملCompact model of magnetic tunnel junction with stochastic spin transfer torque switching for reliability analyses
Spin transfer torque magnetic tunnel junction (STT MTJ) is considered as a promising candidate for non-volatile memories thanks to its low power, high speed and easy integration with CMOS process. However, it has been demonstrated intrinsically stochastic. This phenomenon leads to the frequent occurrence of switching errors, which results in considerable reliability issues of hybrid CMOS/MTJ ci...

The response of a neuron to a linear combination of the first two harmonics of a fundamental frequency is studied by means of a leaky integrate and fire model. A suitable modification of the classical stochastic model is introduced to consider such input. The resulting interspike interval distribution exhibits maxima in correspondence with the fundamental frequency that was absent in the input ...

Spiking Neural Networks (SNNs) have emerged as a powerful neuromorphic computing paradigm to carry out classification and recognition tasks. Nevertheless, the general purpose computing platforms and the custom hardware architectures implemented using standard CMOS technology, have been unable to rival the power efficiency of the human brain. Hence, there is a need for novel nanoelectronic devic...
